We conducted two lexical decision experiments and one replication study to examine the scope of transposed-phoneme effects when the transposition involves non-adjacent phonemes. The critical stimuli were non-words derived from a real word (the base-word) either by transposing two phonemes or by substituting the same phonemes with different phonemes. In Experiment 1, the transposed phonemes belonged either to the same syllable (e.g. /bis.tɔk/ for the French base-word /bis.kɔt/) or to a different syllable (e.g. /ʃo.lo.ka/ for the French base-word /ʃo.ko.la/) and were located either at the beginning of the speech signal (e.g. /sib.kɔt/ for /bis.kɔt/; /ko.ʃo.la/ for /ʃo.ko.la/) or at the end (e.g. /bis.tɔk/ for /bis.kɔt/; /ʃo.lo.ka/ for /ʃo.ko.la/). Experiment 2 compared within-syllable and between-syllable transpositions derived from the same set of bi-syllabic base-words (e.g., /sib.kɔt/, /bik.sɔt/, /bis.tɔk/ for the base-word /biskɔt/). In both experiments, we found clear transposed-phoneme effects with longer "no" decisions for transposed-phoneme non-words compared with the matched substituted-phoneme non-words. The effect was of similar magnitude when the transposed phonemes occurred in the same syllable and across different syllables. Also, for both the within- and between-syllable transpositions, the size of the transposed-phoneme effect did not vary as a function of the position of the transposition. Overall, our results suggest that phonemes can migrate across their respective positions not only within a syllable, but also across syllables. More importantly, they also suggest that position-independent phonemes exert a continuous influence during the entire processing of the auditory stimulus to the extent that there is sufficient time for this influence to manifest itself.
我们进行了两项词汇判断实验和一项重复研究，以考察当音位换位涉及非相邻音位时换位音位效应的范围。关键刺激是通过换位两个音位或用不同音位替换相同音位从一个真实单词（基础词）派生而来的非单词。在实验1中，换位的音位要么属于同一个音节（例如，法语基础词/bis.kɔt/的/bis.tɔk/），要么属于不同音节（例如，法语基础词/ʃo.ko.la/的/ʃo.lo.ka/），并且要么位于语音信号的开头（例如，/bis.kɔt/的/sib.kɔt/；/ʃo.ko.la/的/ko.ʃo.la/），要么位于结尾（例如，/bis.kɔt/的/bis.tɔk/；/ʃo.ko.la/的/ʃo.lo.ka/）。实验二比较了源自同一组双音节基础词的音节内和音节间换位（例如，基础词/biskɔt/的/sib.kɔt/、/bik.sɔt/、/bis.tɔk/）。在两个实验中，我们都发现了明显的换位音位效应，与匹配的替换音位非单词相比，换位音位非单词的“否”判断时间更长。当换位音位出现在同一个音节和不同音节中时，效应大小相似。此外，对于音节内和音节间换位，换位音位效应的大小都不会随着换位位置而变化。总体而言，我们的结果表明，音位不仅可以在一个音节内跨越各自的位置迁移，还可以跨音节迁移。更重要的是，它们还表明，位置独立的音位在听觉刺激的整个处理过程中都会持续产生影响，只要有足够的时间让这种影响显现出来。
